2. Tomás compró una bicicleta en $199.900. Primero, canceló la mitad y el resto en 7 cuotas de igual valor, con un interés total
Papessa [141]

Answer:

Cada cuota tendrá un valor de $14,850.

Step-by-step explanation:

Dado que Tomás canceló la mitad del valor de la bicicleta, la cual costaba $199.900, el valor pagado al inicio fue de $99,950 (199,900 / 2).

Luego, para el valor restante, Tomás suscribió a una financiación con un interés de $4,000, elevando el monto a pagar a $103,950, pagaderos en 7 cuotas. Por lo tanto, dichas cuotas tendrán cada una un valor de $14,850 (103,950 / 7).

Suppose it takes John 41 minutes to run 4 miles. How long would it take him to run 8 kilometers? Round your answer to the neares
Pani-rosa [81]

Answer:

51 minutes!

Step-by-step explanation:

<em>Hello there fellow human!</em>

First off, you convert kilometers to miles.

1 kilometer = 0.62 miles; therefore, 8 kilometers = 8*0.62 = 4.96 miles

Next, you determine how many minutes it takes for John to cover 1 mile

which is gotten by dividing 41 by 4;  

41 / 4 = 10.25. So it takes 10.25 minutes to cover 1 mile. (minutes per mile)

Next, you multiply the number of minutes taken to cover <em>1 mile (10.25)</em> by <em>4.96 miles (8 kilometers)</em>,  10.25 * 4.96 = 50.84 minutes. Rounding that to the nearest minute, you get 51 minutes which make sense because the amount of time taken to cover 4 miles (41 minutes) will be shorter than the time taken to cover 4.96 miles (50.84 minutes) since 4 miles is smaller than 4.96 miles. DIRECT PROPORTION

All calculations where done with a calculator. If you don't have that, you can always divide manually and convert to fraction.

Emma is training for a 10-kilometer race. She wants to beat her last 10-kilometer time, which was 1 hour 10 minutes. Emma has al
Sauron [17]

Answer:

70 > I+55

Step-by-step explanation:

The last inequality expresses better this situations.

Emma wants to beat her last record, which was 70 minutes. So, she needs to run in less than 70 minutes.

However, she already ran 55 minutes, the remaining time would be the variable I, so, the sum of them must be less than 70 minutes. So, there are two options to represent this:

I + 55 < 70 or 70 > I + 55.

And if this helped you, feel free to make this the brainliest answer!
